封闭式水系统全年空调的构思与分析

提出了一种可使用水冷冷水机组同时实现夏季制冷和冬季供暖的集中空调系统冷热源方案，该机组夏季可利用水冷冷水机组制冷系数高的特点而冬季又能以热泵方式工作。初步分析表明在中南部地区其全年能耗低于空气源热泵机组。

Analysis and conceiving of year-round air conditioning with a closed cooling water system

Presents a cold and heat source scheme for the central air conditioning system that can use water-cooled chillers for cooling in summer and heating in winter. It has advantages of high performance coefficient of water-cooled chillers in summer and working as heat pump in winter. Primary analyses indicate that its annual energy consumption is less than that of the air-source heat pump units in Middle and South China.
